This is part of an old two piece unit (PV-9600A). The tuner section
(PV-A860) will not power up. The front panel does not light up. Here is what
I have found so far:

R10 Burnt, measures 1.6K out of ckt (I this the correct value?)
Q5 2SD1051-R no good
Q6 2SB642-R leaky? seems to be a high gain type transistor, but not a
Darlington
D7 8.2 volt zener shorted

Are there any other components that I have missed, and can someone confirm
R10s value.

Thanks

This is a followup to the origional post. I have ordered the faulty
components but am still unsure of the value of R10.

Anyone know?

Thanks
